Chapter One

Thor, supreme commander of the Asguard fleet, carefully maneuvered his spacecraft into geosynchronous orbit with Earth. He had been performing a routine check of a Protected Planet when his ship picked up strange readings on an uninhabitable planet in the same system. He quickly beamed the object aboard his ship and, recognizing the ruins as what the Asguard had given to a specific race of humanoids on earth, rushed to beam the only person he knew who could tell him its purpose.

"THOR!" rang across the ship as four people found themselves in various stages of undress and in the same room. The men of SG1 found themselves staring at an almost naked Major Samantha Carter. Since this has happened before, they only gave her body a cursory glance before all six eyes glues themselves to a black tattoo on her left arm. It seemed to be moving. For her part, Samantha pulled her shirt back on so fast it may as well have been magic. Fortunately for her, Thor once again beamed the team away. This time to a large, sterile, white room with a dirty veiled arch in the center. Samantha carefully approached the arch, hearing for the first time in over a decade the whispers of the runes carved on both sides. The whispers that promised a slow death of suffocation to a condemned prisoner. She made the situation well known to her team with a succinct, "Fuck!"

Samantha Carter was a woman of secrets. She led a secret life, had a secret job, and was completely cut off from her own society because of them. But none of these things could compare to the secret she had been desperately keeping from her team, SG1. That Secret? Samantha Carter is not a Carter at all. Her real name is Samantha Black-Potter, Head of the Most Ancient, Most Noble House of Potter, and wife of Inner-Circle Death-Eater Regulus Black.

She was pulled from her musings on how to explain the Arch to Thor and to Colonel O'Neill when the runes flashed, not once but four separate times. "What was that?" Dr. Daniel Jackson asked his half-dressed friend. Her only response was to swear again, and to pull a…stick...out of her sleeve. Samantha bodily pushed the three men back from the arch, her wand pointed at the veil covering it as an unconscious man tumbled through. She quickly relieved him of his own wand and drug him away from the opening, barely making it back to in front of her defenseless team as three more people stumbled out. The first through, a gaunt woman with wild hair and wilder eyes, was positively flying- she barely regained her feet before staring around the sterile room, dazed. The two that followed her emerged at a more sedate pace, one was male, about 15, and the other female, about 20. The boy, with messy black hair and glinting green eyes HAD to be her nephew, Harry Potter. However, Samantha knew that Albus Dumbledore had told her father that Harry had died with his parents. Obviously, someone was misled, and she doubted that that person was Dumbledore. She barely spared a glance at the young woman, except to note that her hair was a pinkish-purple, and instead focused her attention on the crazed woman in front of them. Her old Dorm-mate, prank partner, and best friend from school, Bellatrix Black Lestrange.
